Question : A is thrice as good a workman as B and together they can finish a work in 32 days. In how many days will B alone complete the same work?
Option 1: 96 days
Option 2: 104 days
Option 3: 112 days
Option 4: 128 days
Correct Answer: 128 days
Solution : Let A take $x$ days to complete the work. Then, amount of the work completed by A in 1 day = $\frac{1}{x}$ Then B would take $3x$ days to complete the work. Then, the amount of the work completed by B in 1 day
Question : The average weight of the 25 members of the group is 39 kg. The average weight of 27 members of another group is 21 kg. What will be the total weight of the members of both groups?
Option 1: 1426 kg
Option 2: 1542 kg
Option 3: 1507 kg
Option 4: 1714 kg
Correct Answer: 1542 kg
Solution : The average weight of 25 members of a group = 39 kg Total weight of 25 members of a group = 39 × 25 = 975 kg The average weight of 27 members of another group = 21 kg Total weight of 27 members
Question : The largest six-digit number is divisible by 198, if the digits are rearranged, even then the number will be divisible by:
Option 1: 3
Option 2: 6
Option 3: 2
Option 4: 66
Correct Answer: 3
Solution : Largest six-digit number = 999999 Dividing by 198, we get: Quotient = 5050 Remainder = 99 $\therefore$ The largest six-digit number divisible by 198 = 999999 – 99 = 999900 If the digits are rearranged, Sum of all digits of the number = 0 +
Question : If $x$ men can do a piece of work in $x$ days, then the number of days in which $y$ men can do the same work is:
Option 1: $xy$ days
Option 2: $\frac{y^{2}}{x}$ days
Option 3: $\frac{x^{2}}{y}$ days
Option 4: $x^{2}y$ days
Correct Answer: $\frac{x^{2}}{y}$ days
Solution : Given: $x$ men can do a piece of work in $x$ days. We know the concept $M_1D_1=M_2D_2$, where $M_1$, $M_2$ are the persons and $D_1$, $D_2$ are the number of days. According to the question, ⇒ $x×x=y×D_2$ $\therefore D_2=\frac{x^{2}}{y}$ days Hence, the correct answer
Question : What will be the amount received on Rs. 25000 at the rate of 20% per annum compounded yearly for 4 years?
Option 1: Rs. 51840
Option 2: Rs. 50350
Option 3: Rs. 53550
Option 4: Rs. 48750
Correct Answer: Rs. 51840
Solution : Given: Principal, P = Rs. 25000 Rate of interest, $R$ = 20% Time, $T$ = 4 years Now, A = P$(1+\frac{R}{100})^T$, where P is principal, $R$ is the rate of interest compounded annually for $T$ years. ⇒ A = 25000$(1+\frac{20}{100})^4$ = 25000$(\frac{6}{5})^4$ = 25000$×\frac{6}{5}×\frac{6}{5}×\frac{6}{5}×\frac{6}{5}$
Question : Directions: If ‘+’ means ‘–’, ‘–’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’, then what will come in place of the question mark (?) in the following equation?
124 × 4 ÷ 13 – 3 + 36 = ?
Option 1: 31
Option 2: 34
Option 3: 45
Option 4: 42
Correct Answer: 34
Solution : Given ‘+’ means ‘–’, ‘–’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’ 124 × 4 ÷ 13 – 3 + 36 = ?
After interchanging the mathematical operations the equation becomes – 124 ÷ 4 + 13 x 3 – 36 = ? 31
